Hell yeah. I just keep a fan blowing on mine and my temps are nice, a cool tube would eliminate almost all heat besides the ballast and it doesn't get too hot. Do you have an outtake?guy's was forced to get a tent due to smell. Would like to switch from 192w T5 to 400w cool tube. The tent is 3x3x6 would a 4 inch inline fan with a carbon filter keep it cool enough with the cool tube?
Your 400 watt would be great.I'm prob never going to have more than 2 plants. But money is not any object, if my current run doesn't get me a zip and a half off each I'll go 400w cool tube. It actually would take up a bunch less room in the tent than my 2x2 8 bulb T5.
thanks
